The correct sequence of occurrences of rivers from Chennai to Kolkata when travelled by road along the east coast is Penneru, Krishna, Godavari, Mahanadi, Subarnarekha.
Travelling northwards from Chennai (Tamil Nadu) along the east coast through Andhra Pradesh, Odisha, and into West Bengal, the major rivers crossed in sequence are the Penneru (or Palar near Chennai), then the Krishna, followed by the Godavari, then the Mahanadi in Odisha, and finally the Subarnarekha river which forms the border between Odisha and West Bengal, before reaching Kolkata.
The Kaveri river is south of Chennai. The Periyar river flows westwards into the Arabian Sea from Kerala, not relevant for a Chennai to Kolkata eastward journey. This sequence reflects the major river systems encountered when moving north along the eastern coastal plains of India.
